目前,宽带网接入方式多种多样,凭着IP技术的广泛流行及以太网设备的高性价比的特点,以太网接入成为各运营商在用户宽带接入网的重要手段之一。传统的以太网接入是将原有企业网模式放大,而企业网与宽带IP接入网之间存在很大的区别。企业网无需计费,而宽带接入网是一个由运营商提供的公用的网络环境,必须提供认证、计费、用户管理和带宽管理等功能。因此,面向公众服务的宽带技术应具有较强的可运营及可管理性功能,同时有用户可管理、用户业务多样性、认证计费灵活性、用户信息及网络安全性等特点。
At present, broadband access varies widely. With the widespread popularity of IP technologies and the high cost performance of Ethernet devices, Ethernet access has become an important means for operators to access broadband networks in subscribers. The traditional Ethernet access is to enlarge the original enterprise network mode, and there is a big difference between the enterprise network and the broadband IP access network. Enterprise network without billing, and broadband access network is a public network provided by the operator network environment, must provide authentication, billing, user management and bandwidth management functions. Therefore, the broadband technology for public service should have strong operational and manageability features, such as user management, diversity of user services, authentication and charging flexibility, user information and network security.
